I have a 07 convertable, I want to change out the exhaust for performance and sound. I have been looking at Magnaflow,Corsa Touring,Corsa Racing Indy . I want a system that have a great sound but no drone while crusing any suggestions

 

I have a Borla Exhaust and I think it sounds amazing. It has more rumble than stock but isn't obnoxiously loud!

 

I have been very pleased with the Magnaflow 15886 model axle back exhaust on my 2007. Great American Muscle car sound and no issues with drone on the highway.

I have a NEW in the box set up for sale in the parts section. Lets make a deal on it.

 

Thanks for the feed back..... have a great holiday

 

If you want performance and sound skip the catbacks and just get a set of headers. Catbacks will give you zero hp increase. A set of headers will get you 25-40rwhp w/tune and give your car a more aggressive tone.

 

corsa sport exhaust + kooks headers = Very Nice Sound!

 

I've got an '05 'vert.....originally installed Corsa Sports with X-Pipe. Exhaust sound was great with no drone, but not much in the way of performance improvements. Then installed AR headers with hi-flow cats & kept the Corsa mufflers, plus a tune by Doug Ring at ECS. Difference was outstanding....much better power without having to do any internal engine mods plus even better sound (at least to my ears).

 

Anytime you change out a big chambered muffler for a straight thru you will get gains. Maybe not as much as the headers but still some gains, due to less flow restrictions. Besides when you free the air flow from the intake to the headers, why have a bottle neck at the mufflers?

Plus all the others have said whatever they did plus tune to get their gains, so a CBE/axel back and tune will gain too. I bet just an axel back and tune will net 20 hp.

 

Corsa is high pitched European sound (I don't like it) with little or no drone. Bullets have a great deep rumbling muscle car sound and lots of drone. Best of both worlds is dual mode.

 

With everything else stock the B&B PRTS have no drone, or very very little depending on your definition of drone, and are suppose to help keep the drone down when doing headers. I have the PRTs and they are like a Harley sound in a V8, love it. When I do the headers and catted x-pipes I will probably have a resonator added in too.

 

Nxt step exhaust. New company amazing price, quality and sound. Give it a try

 

The mufflers are not as much of a bottle neck as you think. Plus I don't believe the OP has any other mods. The minimal (if any) gains a catback will get on a stock car are hardly worth the cost. An axle-back system is a little cheaper but then provides even less (less than nothing?) gains because you're keeping the stock Y/X-pipe. A tune isn't necessarily required with headers but is strongly recommended. However, you will see gains regardless. To say an axle back + tune will net 20rwhp you'd probably be correct. 99% of that gain would be from the tune though. You could swap a catback system on a stock car and not see any substantial changes to the airflow measurements. (this is 3rd party knowledge on my part though but it is based on research of other shops and tuners I have spoken with)

Now if he wants it just for sound then that's a different discussion. If there's a concern about the warranty then again that's another discussion. But with catbacks costing $1200-1500 new ($500+ used), axle backs costing $400-600 new ($200+ used), and headers costing $1500 new ($700-1000 used) and tunes ranging from $200 mail order- $500 dyno you really have to rethink the cost vs gains here. For performance AND sound, headers are the only way to go.

 

No exhaust mod is worth the money in terms of how much the actual cost of making the item was compared to what is paid. And going from a chambered muffler to a straight thru will result in gains, just smaller compared to others. Id say the same as an intake mod. But if you are opening the flow then open the flow all the way. Id say its as important as the x pipe and intake. As others have said that when they do headers and all the dyno is after the tune, which probaly accounts for a great deal of the gains. A tune and CBE/axel back will net a good amount. Im not sure if there has been a dyno with just headers and no tune or no other mods, and what the gains were. One thing we saw in my other cars forum was, the first flow mod done was usually the biggest gainer, and consecative mods were minimal no matter which order they were done in. A CBE as a first mod on my 370Z netted 20 hp. But I agree the axel back wont be a great gain but minimal but the sound is part of it too, and sometimes looks. I say if you do the intake, headers, x pipe, you might as well do the axel back and get that last few hp.

 

vs.



got to be less restrictive than the first.

I would say kinda like the difference between stock intake and the vararam.

 

WOW... I cant beleive all of the nhelp and quick responce... Thanks to all... sounds like headers are the way to go..... I guess I will need to do some research on that....

 

Good idea, Im still trying to decide if I want to or not. From what I can tell you can run headers without a tune but a tune will dial in the car to optimal levels and gain even more power. Just dont kow if I want to mess with GM and their warranty stuff. What Im doing (if I get them) is sticking with the same vendor for the headers and x-pipe as they are supposibly made to work well with the axel back I already have, in terms of keeping drone down. I may have a resonator put on too to help ensure the drone is at its least. I also have to find out here in TX if they will fail you on a visual inspection or not.

 

If you pick out a set up let me know on what you decide..... I would be concerned about the warranty as well. I have an extended warranty for the next 5 years... I assume headers will void that?
